MISHIMOTO Honda Civic Performance Radiator, 2001-2005 (non-Si)

The Mishimoto Performance Aluminum Radiator for the 2001–2005 Honda Civic is engineered as a direct‑fit upgrade to improve cooling efficiency and long‑term reliability. The factory radiator is adequate for daily use, but its plastic end tanks and limited core capacity become weak points as the vehicle ages or sees spirited driving. Mishimoto addresses these shortcomings with a lightweight dual‑core aluminum design that enhances heat dissipation and stabilizes coolant temperatures.

Constructed from 100‑percent brazed aluminum with polished end tanks, this radiator provides increased durability and improved thermal performance. The expanded core surface area promotes faster coolant‑temperature recovery, reducing the risk of overheating during demanding conditions. Each radiator includes a high‑pressure 1.3‑bar Mishimoto radiator cap to raise the boiling point and optimize cooling‑system efficiency.

This unit is a direct OEM‑fit replacement and pairs perfectly with the Mishimoto Fan Shroud Kit for maximum airflow and cooling stability. As with all Mishimoto components, it is backed by the Mishimoto Lifetime Warranty.
